RBN Energy: could refinery adjustments to handle more light crude be a bust? This is another very important article for those trying to get a better understanding of the US shale revolution. This is a keeper. The article will be archived at the source.
The deluge of light (and super light) sweet crude from U.S. tight-oil plays like the Permian Basin, Bakken and Eagle Ford has had many effects, including a push by refiners to rework facilities designed for heavy-crude processing to handle an excess of lighter oils. Many of these projects are underway and expected online in the next two years. Today, we consider refinery infrastructure investments that might not pan out in a low crude price world.
Everyone--even those whose interest in the oil industry extends only to how much they pay for gasoline or heating oil—knows that U.S. oil production has risen significantly over the past few years (from 5.6 MMb/d in 2011 to 8.7 MMb/d in 2014, and 9.3 MMb/d as of June 2015). You need to be something of a petro-geek, though, to know that almost all of the increase in domestic production the past few years has come in the form of lighter, sweeter crudes, especially very light oil with American Petroleum Institute (API) gravity of between 40 and 50 degrees. (Crudes with API gravity between 32 and 40 degrees are typically categorized as light, while heavy crudes--say, diluted bitumen from the Alberta oil sands--have gravities below 22 degrees, and medium oils have API gravity of between 22 and 31 degrees.) Refineries are designed and built to operate most efficiently when processing a certain type or mix of crudes, and a lot of refinery upgrades in the years leading up to the Shale Revolution were intended to accommodate a world where lighter crudes were thought to be running out, to be replaced by heavier (lower API gravity) crudes – particularly on the Gulf Coast. There is still plenty of heavy crude out there that comes to the Gulf Coast – from Mexico and Venezuela for example and also Western Canada. But with the U.S. producing a surfeit of light crude and with prices for that light crude being discounted – refiners began to consider investing in functionality to improve their light crude processing capacity.
Production in “light tight” oil plays like the Permian, Bakken and—most pertinent to today’s blog—Eagle Ford (which produces the lightest crude of them all) has grown exponentially since 2011 and is expected to remain high even under a pessimistic oil-price scenario according to the Energy Information Administration.
